research The Modulatable Stem Cell Niche: Tissue Interactions during Hair and Feather Follicle Regeneration
The document concludes that for hair and feather growth, it's better to target the environment around stem cells than the cells themselves.
research Multi-layered environmental regulation on the homeostasis of stem cells: The saga of hair growth and alopecia
Environmental factors at different levels control hair stem cell activity, which could lead to new hair growth and alopecia treatments.
research Coat condition, housing condition and measurement of faecal cortisol metabolites - a non-invasive study about alopecia in captive rhesus macaques (Macaca mulatta)
Alopecia in captive rhesus macaques is affected by season, sex, age, housing, and stress, with complex links between stress hormones and hair loss.
research Module-based complexity formation: periodic patterning in feathers and hairs
The conclusion is that understanding how feathers and hairs pattern can help in developing hair regeneration treatments.
research Seasonality of Hair Shedding in Healthy Women Complaining of Hair Loss
Healthy women tend to lose more hair in July and April, and the least in February.
research The changes in the hair cycle during gestation and the post-partum period
Hair growth slows and shedding increases after childbirth, but most women don't experience excessive hair loss.
research Ancient Genomes Reveal the Evolutionary History and Origin of Cashmere-Producing Goats in China
Ancient Chinese goats evolved cashmere-producing traits due to selective breeding, particularly in genes affecting hair growth.
research Time-course RNA-seq analysis reveals stage-specific and melatonin-triggered gene expression patterns during the hair follicle growth cycle in Capra hircus
Melatonin affects gene expression in goat hair follicles, potentially increasing cashmere production.
research Associations between season, climate, and pediatric alopecia areata flares in Providence, Rhode Island
Hair loss in children with alopecia areata is more common in winter and linked to climate factors like air pressure and sunlight.
research Variación estacional del tricograma en residentes chilenos
Hair growth cycles in Chileans vary seasonally, with more hair resting in summer and growing in winter.
research The Effect of the Season, the Maintenance System and the Addition of Polyunsaturated Fatty Acids on Selected Biological and Physicochemical Features of Rabbit Fur
Outdoor living and omega-3 supplements improve rabbit fur quality.
research P‐79 Hair follicle growth arrest in Austrian Icelandic horses
Supplementing vitamins and minerals prevented hair loss in Icelandic horses.
research Studies on Abnormal Moulting in the Farm‐Raised Blue Fox (Alopex lagopus)
The farm-raised blue fox had a delayed winter coat cycle and abnormal hormone levels, but its hair growth and hormone changes were still linked.
research Results of 60-second timed hair counts in women between the ages of 20–60 years
The 60-second timed hair count is a reliable and simple way to measure hair shedding at home, showing older women tend to shed more hair than younger women.
research Hair Follicle Development of Rex Rabbits Is Regulated Seasonally by Wnt10b/β-Catenin, TGFβ-BMP, IGF1, and EGF Signaling Pathways
Winter provides the best fur quality for Rex rabbits due to seasonal changes in specific signaling pathways.
research Isolation and molecular characterization of Malassezia pachydermatis from a cutaneous lesion in a California sea lion (Zalophus californianus)
The yeast found in a sea lion's skin lesion was almost identical to that on healthy skin, suggesting environmental factors may affect fungal growth and the cause of the lesion is unclear.
research Effects of Seasonality and Pregnancy on Hair Loss and Regrowth in Rhesus Macaques
Hair loss peaks in spring and regrowth in late summer, with pregnant females losing the most hair.
research Role of Swasthavritta to maintain healthy hair
Ayurvedic practices can help prevent and manage hair problems.
research Coat Problems
The chapter explains causes of hair loss and excessive hair growth in animals.
research Photosensory Function, Reception and Response in Human Skin
Human skin responds to light with protective mechanisms, but more research is needed to understand these processes and their implications for health and therapy.
research Molecular Basis of Maintaining Circannual Rhythm in the Skin of Cashmere Goat
Goat skin adapts to seasonal changes through genes that respond to daylight length, affecting hormone levels and potentially making skin cells light-sensitive.
research British Hair and Nail Society
The document concludes that scalp conditions have various causes and can present in many different ways.
research O13: Interpretation of hair ethyl glucuronide inter-individual factors from large population dataset
Older age increases positive hair alcohol test results, and chest hair is a good alternative for testing; season affects results, with higher levels in winter.
research Abnormal fingerprints and immigration delay disease
Many adult women experience unexplained excessive hair shedding, often starting before age 40.
research Hormonal control of pelage cycles in the short tailed weasel (Mustela erminea bangsi)
The pituitary gland controls seasonal fur color changes in weasels.
research Hoxc13/β-catenin Correlation with Hair Follicle Activity in Cashmere Goat
Hoxc13 is linked to seasonal hair growth in Cashmere goats and is affected by melatonin.
research The effect of melatonin implants administered from December until April, on plasma prolactin, triiodothyronine and thyroxine concentrations and on the timing of the spring moult in cashmere goats
Melatonin implants can change the seasonal prolactin levels and hair growth in adult cashmere goats but not in juveniles, and don't delay spring moult for better fiber harvesting.
research Biologic Rhythms Derived from Siberian Mammoths' Hairs
Mammoth hair grew faster than human hair and showed seasonal changes in growth and mineral content.
research Group-ICA Model Order Highlights Patterns of Functional Brain Connectivity
Choosing the right model order in brain connectivity analysis can affect the detection of differences between healthy individuals and those with seasonal affective disorder.
